Photo of missing 19-year-old shows up on Las Vegas escort website

COLORADO SPRINGS, Colo. (AP) — Investigators say a photo of a missing teen from Colorado Springs has shown up on the website of a Las Vegas escort service, but they don't believe she is the person who posted it.

The Colorado Springs Gazette reported Thursday that El Paso County sheriff's investigators say they have no evidence that 19-year-old Kara Nichols is in Las Vegas.

They didn't say who posted the photo or why.

Nichols was last seen Oct. 9. Investigators say she told her roommate she might go to Denver but left her purse and money.

Authorities describe Nichols as an aspiring model. Sheriff's investigators said last week she might be the victim of a subculture that exploits would-be models. They wouldn't elaborate on what kind of exploitation she might have fallen victim to.
